Description

Device for sealing feed inlet of storage bin and collecting dust
Technical Field
The invention relates to the technical field of storage of bins, in particular to a device for sealing a feed inlet of a bin and collecting dust.
Background
In the technical field of bulk material handling, solid bulk materials need to be fed into silos for storage. When the solid bulk material contains low moisture and powder, a large amount of dust can be raised at the material layer in the bin due to high fall of the material. In addition, the solid bulk material entering the bin can be squeezed out of a part of the air discharging bin, and the part of the air can entrain a large amount of dust to escape from the feeding port. In order to reduce the pollution of dust to the environment.
At present, the conventional method is to arrange an induced draft opening at the top of a storage bin and connect the induced draft opening with a fan through an air pipe. The dust remover is connected behind the fan, and the chimney is connected behind the dust remover. When the fan works, dust is conveyed to the dust remover through the fan along with air, the dust is filtered in the dust remover, and the rest air is discharged out through the chimney. In order to ensure that the dust cannot escape from the feeding port to pollute the environment, the inside of the whole storage bin must be ensured to be in a micro-negative pressure state. However, in the actual production process, especially in the case of large storage bins, a plurality of feed inlets are arranged at the top of the storage bin. And all are not sealed, in order to ensure that the interior of the storage bin is in a micro-negative pressure state, the fan needs to work in a high-load state, so that the engineering investment and the production cost are increased.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a device for sealing a feed inlet of a storage bin and collecting dust, wherein the feed inlet at the top of the storage bin is in a sealed state when not in operation. When the feeding port operates, the automatic opening and the sealing of the feeding closed chute are realized. At this moment, the fan can work in a low-load state, and the interior of the storage bin can be ensured to be in a micro negative pressure state. The engineering investment and the production cost are reduced.
In order to achieve the purpose, the invention adopts the following technical scheme:
a device for sealing a feed inlet of a storage bin and collecting dust comprises a discharge opening sealing device and a feed inlet sealing device positioned below the discharge opening sealing device; the discharge port sealing device comprises a discharge chute, a discharge port sealing chute, a limiting plate and an electro-hydraulic push rod; the electro-hydraulic push rod is arranged on the outer wall of the discharge chute, the end part of the electro-hydraulic push rod is connected with the discharge opening closed chute, the discharge opening closed chute is positioned outside the discharge chute, the limiting plate is arranged between the discharge chute and the discharge opening closed chute, and under the limiting action of the limiting plate, the electro-hydraulic push rod drives the discharge opening closed chute to do linear reciprocating motion;
the feed inlet sealing device comprises a feed inlet sealing chute, a cover plate and a balance weight; the cover plate is hinged at the inlet of the feed inlet closed chute, the counterweight is fixedly connected on the cover plate, the cover plate is closed by the self weight of the counterweight, and the feed inlet is in a closed state; the electro-hydraulic push rod drives the closed chute of the discharge opening to move downwards to jack the cover plate, and the feed opening is in an open state.
The discharge opening sealing device further comprises a base, and a plurality of electro-hydraulic push rods are symmetrically and fixedly connected to the outer wall of the discharge chute through the base respectively.
The limiting plate is in an annular rectangle, the inner side of the limiting plate is fixedly connected with the outer wall of the discharging chute, and a gap is formed between the outer side of the limiting plate and the discharging opening sealed chute.
The feed inlet sealing device further comprises a hinge, the cover plate is composed of an inner side cover plate and an outer side cover plate, the inner side cover plate is hinged to the outer side cover plate through the hinge, the inner side cover plate covers the inlet of the feed inlet sealing chute, and the balance weight is fixedly connected to the outer side cover plate.
The feed inlet closing device further comprises a supporting seat, the supporting seat is fixedly connected to the outer wall of the feed inlet closing chute, and the supporting seat is located below the balance weight.
Under the limiting action of the limiting plate, the electro-hydraulic push rod can drive the closed chute of the discharge opening to do linear reciprocating motion in the direction along the blanking central line. In addition, the limiting plate also limits the dust from escaping from the gap between the discharging chute and the discharging opening sealing chute.
When the feed inlet is not operated, when the balance weight is located on the supporting seat, the couple formed by the balance weight is far larger than the couple formed by the gravity of the inner side cover plate, and the inner side cover plate covers the closed chute of the feed inlet, so the feed inlet is in a closed state.
When the feed inlet is about to operate, the discharging equipment is moved to a fixed-point discharging position near the feed inlet at the top of the storage bin. The electro-hydraulic push rod drives the discharge opening sealing chute to move downwards along the blanking central line, and when the discharge opening sealing chute touches the inner side cover plate, an external couple applied by the electro-hydraulic push rod is larger than a couple formed by the balance weight. The cover plate starts to rotate downwards around the respective hinge until the cover plate does not block the material flow falling position.
When the feeding port finishes operation, the electro-hydraulic push rod drives the closed chute of the discharging port to move upwards along the blanking central line, and at the moment, the electro-hydraulic push rod does not apply force on the cover plate. As the couple formed by the counter weight is far larger than the couple formed by the gravity of the inner side cover plate, the cover plates start to rotate upwards around respective hinges respectively until the counter weight is located on the supporting seat. After the closed chute at the discharge opening is separated from the cover plate, the movable discharging equipment can move to another position close to the fixed point for discharging.
Compared with the prior art, the invention has the beneficial effects that:
1) when the feed inlet is not operated, the feed inlet is in a closed state through the self weight of the balance weight, and the limiting plate limits dust to escape from a gap between the discharging chute and the discharging opening closed chute and is in a closed state.
When the feeding port is about to operate, the electro-hydraulic push rod drives the closed chute of the discharging port to move downwards along the blanking central line to push the cover plate, and the cover plate starts to rotate downwards around respective hinges until the cover plate does not block the material flow falling position; when the feeding port finishes operation, the electro-hydraulic push rod drives the closed chute of the discharging port to move upwards along the blanking central line, and the cover plates start to move upwards and respectively rotate around respective hinges until the balance weight is located on the supporting seat. When the feeding device works at the feeding hole, the feeding device is automatically opened and sealed with the feeding closed chute.
The invention has simple structure and easy control, and can achieve ideal effects of sealing the feeding hole and collecting dust.
2) The dust removal fan can work in a low-load state, and the interior of the storage bin can be guaranteed to be in a micro-negative pressure state. The engineering investment and the production cost are reduced.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings:
the following examples are carried out on the premise of the technical scheme of the invention, and detailed embodiments and specific operation processes are given, but the scope of the invention is not limited to the following examples. The methods used in the following examples are conventional methods unless otherwise specified.
A device for sealing a feed inlet of a storage bin and collecting dust comprises a discharge opening sealing device and a feed inlet sealing device. The discharge opening sealing device is arranged on the mobile discharging equipment at the top of the storage bin, and the feed inlet sealing chute is arranged above the feed inlet of the storage bin.
As shown in fig. 1, the discharge opening sealing device is composed of a discharge chute 1, a discharge opening sealing chute 2, a limiting plate 3, an electro-hydraulic push rod 4 and a base 5.
2 bases 5 are symmetrically and fixedly connected to the outer wall of the discharging chute 1, 2 electro-hydraulic push rods 4 are respectively installed on the 2 bases, the end parts of the push rods of the electro-hydraulic push rods 4 are connected with the top of the discharging opening closed chute 2, and the discharging opening closed chute 2 covers the outer part of the discharging opening of the discharging chute 1.
The limiting plate 3 is in an annular rectangle, the inner side of the limiting plate is arranged on the outer wall of the discharging chute 1, and a small amount of gaps are reserved between the outer side of the limiting plate and the discharging opening sealed chute 2. Under the limiting action of the limiting plate 3, the electro-hydraulic push rod 4 can drive the discharge opening closed chute 2 to do linear reciprocating motion along the blanking central line 111. The limiting plate 3 also limits the escape of dust from the gap between the discharge chute 1 and the discharge-opening-closing chute 2.
As shown in fig. 2, the feeding port sealing device is composed of a feeding port sealing chute 6, a cover plate, a balance weight 8, a supporting seat 9 and a hinge 10. The supporting seat 9 is symmetrically and fixedly connected on the outer wall of the feed inlet closed chute 6. 2 hinges 10 are symmetrically fixed on the top ends of two sides of the feed inlet closed chute 6 respectively, 2 cover plates are hinged to the top of the feed inlet closed chute 6 through the hinges 10 respectively, the cover plates are bounded by the hinges 10, one side right above the feed inlet closed chute 6 is called an inner side cover plate 71, and the other side is called an outer side cover plate 72. 2 counter weights 8 are respectively and fixedly connected to 2 outer side cover plates 72, and the counter weights 8 are positioned right above the supporting seat 9.
As shown in FIG. 2, when the feed inlet is not operated, and the counterweight 8 is seated on the support seat 9, the couple formed by the counterweight 8 is much larger than the couple formed by the gravity of the inner side cover plate 71, and at this time, the inner side cover plate 71 covers the feed inlet sealing chute 6, so that the feed inlet is in a closed state.
When the feed inlet is about to operate, the discharging equipment is moved to a fixed-point discharging position near the feed inlet at the top of the storage bin. As shown in fig. 3, the electro-hydraulic push rod 4 drives the discharge opening sealing chute 2 to move downwards along the blanking central line 111, and when the discharge opening sealing chute 1 touches the inner side cover plate 71, the external couple exerted by the electro-hydraulic push rod 4 is greater than the couple formed by the counterweight 8. The inner cover plates 71 start to rotate downward about their respective hinges 10 until the inner cover plates 71 do not block the material flow falling position.
When the feeding hole finishes the operation, the electro-hydraulic push rod 4 drives the discharging hole sealing chute 2 to move upwards along the blanking central line 111, and at the moment, the electro-hydraulic push rod 4 does not apply force to the cover plate. Since the couple formed by the balance weight 8 is much larger than the couple formed by the gravity of the inner cover plate 71, the inner cover plate 71 starts to rotate upward around the respective hinges 10 until the balance weight 8 is seated on the support seat 9. After the discharge opening closed chute 2 is separated from the inner side cover plate 71, the movable discharging equipment can move to another position close to the fixed point of the feed opening for discharging.
The invention has simple structure and easy control, and is in a closed state when the feed inlet at the top of the storage bin is not operated. When the feeding port operates, the automatic opening and the sealing of the feeding closed chute can achieve ideal effects of sealing the feeding port and collecting dust. The dust removal fan can work in a low-load state, and the interior of the storage bin can be guaranteed to be in a micro-negative pressure state. The engineering investment and the production cost are reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
